Hello, i am a grade 12 physics student and need help with my homework question.

PLEASE MAKE SURE ALL ANSWERS ARE DETAILED. as i am a slow learner. Thank you so much

9. Determine the magnitude and direction of the magnetic force on a proton moving horizontally to the north at 8.6 X 104 m/s, as it enters a magnetic field of 1.2 T, pointing vertically upward. [2 marks] 10. How much work is done against gravity to fire a BOO-kg GPS satellite 200 km into the air? {rE = 6.38 x 106 m, ME = 5.98 x 1024kg) [4 marks] 7. An electron with a velocity of 5.0 x IDEm/s is injected into a parallel plate apparatus through a hole in the positive plate. It moves across the vacuum between the plates slowing down before colliding with the negative plate at 1.0 x 106 m/s. Using the conservation of energy for electric charges, what is the potential difference between the plates? [4 marks] 8. a) Refer to the electrostatic series. A carbon rod is rubbed with silk. Describe the transfer that occurs and the resulting charge that each object has after their interaction. [2 marks] b) What is the difference between charging by friction and charging by contact? [1 mark] acetate glass wool cat fur. human hair calcium. lead silk aluminum cotton paraffin wax ebone polyethylene {plastic} carbon, copper, nickel sulfur platinum. gold weal-l hold on elections increasing tendency to gain electrons strong hold on EIEDIIOHS
